1. doplStatus is incorrectly placed inside curly braces: '{ doplStatus: ...'
2. In your function calls, 'this.data' will do nothing. To access a property of the model you passed as the arrgument: value.someProperty.

1. Curly braces around your function names are only around the 'doplStatus' function. The closing curly brace should be after your last function
2. The way you reference data in your function is incorrect, I gave an example of how to correctly reference a value in my previous reply
